Let's say, you have uploaded 10,000 product photos and decided to resize all of them to a new size. Will you do them one-by-one? Sure no. You can group and tag the uploaded images and apply bulk actions over them. So nice.

Another feature that CSS sprite fans will +1 is the "sprite and auto-CSS-generation". Let's say you have uploaded 4 logo images and tagged them as "logo".

To sum up, Cloudinary is a very useful service for any image processing needs without anything server-side. It will work on any website/server/setup flawlessly as there is nothing to install. Things are very straightforward with almost no coding.

With a web of multiple devices, resolutions and responsive outputs, there are definitely so many opportunities brought by the service.
